World first - Weistec cracks the SLS Black Series TCU (transmission control unit) and has control of the M159 SLS dual clutch gearbox

This is serious business right here and continues to show that the grasp Weistec has on the M156/M159 platforms is unrivaled. The SLS Black Series just like the standard Mercedes-Benz SLS AMG features a dual clutch gearbox. However, the redline on the two cars is different as the SLS M159 V8 revs to 7200 rpm and the M159 V8 for the SLS Black Series was redesigned to rev to a higher 8000 rpm redline for more top end horsepower and tighter gearing.

The dual clutch transmission software of course was also changed in the SLS Black Series to accommodate the higher redline. Not to mention the more aggressive shifting profile for the Black Series. Weistec is able to flash a stock SLS with the Black Series TCU software. This answers a question BenzBoost raised a while ago when the SLS Black Series came out regarding if one could retrofit Black Series parts and software to the standard SLS. It certainly is appearing increasingly more likely that SLS owners will be able to update their cars with the newer AMG parts and software.

Expect a release with the product information and cost in the coming weeks. Weistec is testing the M159 V8 in the standard SLS to see how it reacts to the increased RPM as far as longevity and durability is concerned before officially releasing this software. The custom Weistec coded TCU software requires an ECU flash to function correctly as well.

This is a pretty big deal. Especially as the SLS contiues to fall on the secondary market. There is no reason now to get the SLS GT is you can get Black Series software for the SLS. It makes it a value...

How does the sls transmission compare to dct or pdk? If shift speeds are comparable, then a weistec stage 3 sls would DEFFITELY be a bargain supercar slayer.

It is a dual clutch so it's fast. The standard SLS has a somewhat lazier profile so old women can drive it. The SLS GT sharpens up the shift speed a bit and the Black Series is more aggressive than either. I don't see why the Black Series would be any slower than others.

not yet!
Weistec are finding soloutions with SLS's that are equipped with longtubes headers.
they will be developing headers for the SLS that works with thier SC systems.
My bro ran with a stage2 SC SLS runining with the same headers that he has and was dead even with it.
That particular SC SLS belonged to a friend of mine and weistec worked on it in Cali before he shipped it to Qatar. Its a bummer that he sold it though. I kind of wanted him to wait for Weistec's developments on the SLS to get his car running faster

So you're saying a normally aspirated SLS is as fast as a blown SLS ? LOL, yeah, I'm gonna have to call bull$#@! on that one. And please don't tell me I have no clue what I'm talking about because I'm fully aware of the header issue regarding O2 placement on the SLS.

Let's all try to not be so combative.

A blown SLS will be faster than a naturally aspirated SLS. There is nothing to discuss here really.

Early on the kits were getting kinks worked out and I remember one guy with headers complaining about some stuff. Regardless, Weistec has this all tested and sorted and the SLS with a blower just flat out rips.

I'm not being combative, I just called bull$#@!. So did you, but in a nicer way.
Regardless of what header issues on the SLS existed early on, there's no way the problem (or, "kink" as you referred to it) could be so massive that it would negate the blower's increased hp 100%. But that's pretty much what this guy would like us to believe and personally don't like it when people post $#@! that insults the collective intelligence of everyone here.

I realize this Luke but these threads tend to turn into you versus them when going down this route and considering this is a thread tied to a vendor it will be kept very tightly on topic by me and will not move off track with petty fighting. Anything superfluous will be negged into oblivion and/or deleted. Period.

You are correct, a blown SLS is way more powerful. There is no way an NA SLS can win, ever. It can be modified of course with say this upcoming Weistec TCU and revved out to make more power but you can't increase boost. You can probably now increase the redline along with boost if you have an SC which should make the SLS vicious and in all honesty more like what I like about the M3. It essentially revs like an M motor but with more displacement. The best of both worlds.

The M156 already revved pretty high for a big V8 but going to 8k RPM makes a huge difference if the torque curve stays flat. I don't know if cams are in the works or not or if the Black Series cams and valvetrain can be retrofitted but I would think so. So blower, plus more rpm, faster shifts, means an SLS is incredibly appealing. I really want one now with the prices dipping in the 13X,XXX range for the first year models.

I'm glad you agree. And I have no intention of derailing a vendor thread, especially one I know so well. I was simply pointing out that there is no way a N/A SLS is going to be anywhere close to a blown SLS and anyone suggesting otherwise is just not being honest.

I just want to point out the tuning on the SLS has evolved and the M156 and M159 have significant differences. A healthy blown car will always win though.
